if you have a spare PSU, you could just put that psu on that disk alone, and 
hotwire the header plug to start the psu voltages, to pre-power your disk 

then proceed and see if that's really the issue.

other ideas: 
1) the onboard fakeraid is getting initialized and has an effect on it (check 
bios after plugging disks in)
2) the 7th and 8th port alone is a different chipset and has some weird issues, 
like when 8th port is plugged, 7th starts failing
3) i guess software is always possible, but i would start eliminating all the 
hardware issues

btw: what happens if you add the 3TB once more? will the reallocated sectors 
show up again? (i wonder)

if all this fails, i'd send an email to lkml to get more ideas or ways to 
check it.
